Abstract

An injection syringe having a body (12) bearing an injection needle (14), a reservoir (16) containing a liquid (42) to be injected and being movable relative to the body (12) for causing the liquid to be injected to circulate through the needle (14), and a needle shield (18) movably mounted relative to the needle (14) for movement, under the control of a spring (20), from a retracted position towards an active protective position. The syringe has complementary parts (54, 62) which, when engaged, retain a first spring (20) end cooperating with the shield (18), and which, when disengaged by further movement of the reservoir (16), release the spring (20) first end to displace the shield (18) to its active protective position. The second spring (20) end is pressed against the reservoir (16) for gradually compressing the spring (20) during injection.
